1、Designation: D 1555M 08METRICStandard Test Method forCalculation of Volume and Weight of Industrial AromaticHydrocarbons and Cyclohexane Metric1This standard is issued under the fixed designation D 1555M; the number immediately following the designation indicates the year oforiginal adoption or, in

2、the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This standard is for use in calculating the weight andvolume of benzene, toluene,

3、mixed xylenes, styrene, ortho-xylene, meta-xylene, para-xylene, cumene, ethylbenzene,148.9 to 176.7C and 176.7 to 204.4C aromatic hydrocarbons,and cyclohexane. A method is given for calculating the volumeat 15C and 20C from an observed volume at tC. Table 1 liststhe density in grams per cubic centim

The values stated ineach system may not be exact e

5、quivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the use

The data support-ing this conclusion appears to be unavailable at the

12、 presenttime; however there is no reason to change this recommenda-tion. If, depending on the composition of the impurities, thereis reason to suspect that the VCF implementation procedurespresented below do not apply to a particular impure product, aseparate implementation procedure should be indep

This may be done by measuring the density of arepresentative sample at different temperatures throughout theexpected working temperature range, regressing the data toobtain a temperature/density equation that best reproduces theobserved data, and then dividing the constants of th
